Descrição do produto: Fluke 1621 Kit - Basic Earth Ground Tester

The Fluke 1621 Kit is an easy-to-use earth ground tester. For ground resistance testing, the 1621 Kit is the first line of defense in detecting reliable ground connections. The unit features basic ground testing methods including 3-pole Fall-of-Potential as well as 2-pole ground resistance tests. Its convenient size, rugged holster, and large, clear LCD display make it an ideal field earth ground tester, for most electrical grounding work environments. With a simple user interface and intuitive functionality, the Fluke 1621 Kit is a handy grounding tool for electrical contractors, utility test engineers, and earth ground specialists.

1. If the tester is not going to be used, or is being stored for a long period, remove the battery and store separately from the tester to avoid damage from battery leakage.2. The four temperature ranges for the tester exists to satisfy European Standards requirements; the instrument can be used over the full working temperature range by using the temperature coefficient to calculate accuracy at the ambient temperature of use.3. Covers all deviations caused by influence quantities E1-E5. If the deviation E4 caused by high probe or auxiliary probe resistance is higher than specified flashes. Measured values are outside of the specified operating uncertainty.
